Shocked at quality!
Shocked at quality! Everything was to size and very comfortable, and surprisingly thick quality material. Would purchase again. I am very content with the quality and the price.

Best quality
Always excelent quality. The best underwear for young men. I've been buying this underwear for about 10 years. It's going to be hard for my son to let them go. Plain colors are perfect!!

Never buying any other undies
My 4 year old has exclusively worn these since we stopped diapers!! They hold up great in multiple washes and roughhousing.

Repeat purchase
This is the third time I’ve purchased these as my kid grows. He says they are comfortable and reaches for them over other brands, they’ve worn well, and fun colors.

Super comfortable underwear
We have s very skinny 5yo who had sensitive skin and still runs through underwear rather quickly. Finding him comfortable options has been hard, but he loves these.

My kid is obsessed...
My son wanted to try boxer briefs, and these are a winner! He loves the colors, they are super comfortable, and they look cute too! Now he doesn't want to wear anything else. I know another purchase is in our future!

Soft Undies for Big Kids
Great undies for my 10 year old son. They are very comfy and soft. I think they run a tiny bit small.

Best underwear ever!
My kids adore these underwear. So comfortable. They are both on their second packs because they grew out of them— but they are such great quality that even after being washed and dried once a week for 2ish years, they still looked great. Thanks for having solid color options so that my 12 year old continues to want them even though he won’t wear stars and rainbows anymore.

Our standard wardrobe set
Love the solid colors. Would happily pay a bit more if they are organic cotton.

Best undies!
Of all the boxer briefs my son has tried over the years, these are by far the best. Not too tight, not too loose. Simple colors.

Soft and fits great
Really soft boxer briefs, we’ve used these for years and worth the high price tag (I wait for sales). They last a long time, he grows out of them without them fraying or the elastic getting loose. My one con is Primary is known for their tagless clothing. All underwear have a small tag on the side showing the date they were manufactured, and it’s not easy to get off.

Boxer 7-pack
love the colors. Since a Xmas gift, I cannot comment on the fit at this time. However, I also bought sunshine yellow hooded zip in Size 5-Toddler. Arrived but has 3 stains on the side. Very disappointed as this color is one of my grandson's favorite!

Best undies ever!
Bought for grandsons who like these over any other underwear they have had. They wear the same size and divided them up themselves. They take turns with the "weird one"-for some reason they think it's so funny that there is and a gray pair!
